The 920-139 exam is the official Nortel exam for Nortel NCDS Multimedia Communication Server(MCS)5100 3.0. Passing it earns you the NCDS (Nortel Certified Design Specialist) credential, which sits at the Specialist level. It is also connected to Nortel Certified Support Specialist (NCSS), Nortel Certified Technology Specialist (NCTS), so what you learn carries over if you plan to pursue those paths as well. Employers treat the certification as verified proof of skill, which is why structured preparation with 2Pass4sure's practice questions pays off.

The 920-139 exam contains 60-72 questions, and the time limit is 90 minutes. Translate that into a pacing plan before exam day: know roughly how long you can afford per item, flag anything that stalls you, and circle back at the end instead of burning minutes. Two or three full timed sessions in 2Pass4sure's test engine will teach you that rhythm far better than untimed reading ever will.

The passing score for the 920-139 exam is 70%, and the official registration fee is USD $125-$150. Remember that a failed attempt means paying that fee again in full for a retake, so treat self-assessment as part of the budget: run 2Pass4sure's practice questions under timed conditions and only book your seat once your scores sit comfortably above the passing bar.
